3 Claims. (Cl. 2MP-1391) This invention relates to portable hoists 'andis `particularly adapted to be used in connectionv withV the handling ofexcavated dirt, markers and theA like in cemeteries.

The primary object of the invention is to mount a hoist upon wheelsadapted `to handle burial vaults and thev like by straddl-ing graveopenings.

Another object of the invention is to providea hoist mounted on wheelslthat can-be moved about by hand or trailedl lbehind tractors orvehicles. Y

Another object of'theinventfion isto 'provide a movable hoist adapted tosupport a boxffl-ikeV container used in the transferring of dirt re-`moved from graves to-a upoint Iadjacent Athegra-ve. A further object ofthe invention is 13o-providemeans for dumping ythe container and itsvcontents into the grave after the vault has 'beenlowered by the said'hoist.

A still further objeotofv` the i'vention is the provision of meanswithin the hoist for increasingV its lifting power while under heavyload and increasing its speed of operation under light loads.

.And a.stifllturtherlobjectnof theinventionis to provide a hand brakecontrol. mechanism. foru controlling the Yhoist when being moved by handfrom place to place.

These and other incidental objects will be apparent in the drawings,specica'tion and claims.

Referring tothe drawings: ,A Figure l isa'sideview of our-new andimprove portablel hoist. y

Figure 8 is an end sectional view, taken on line 8 8 of Figure 2.

Figure 9 is an enlarged detail sectional view, taken on line 9 9 ofFigure 5.

Referring more specifically to the drawings:

Our 'new and improved `portable* hoist consists of aliorizontal U-shapedframeA I;,consist'ingV 0f the tubular sidev membersz terminating 'inthe" cross channelV member 3y by anysuitable'moan's, as for4 instancewel-ding. ExtendingJ upwardly from the sidek frames 2 are apairofpedestalsil. These pedestals may be wel-ded to the-side frames 2 at 5'having recnforcing gussets 6- associated.-V

therewth; Running' from the forward@ end ad jacent 'the cross channel land approximately at a forty-five degree angle are bracing frames 1connecting the upper ends of thepedestals' `#with the side frames `2,best illustrated` in Figure 1;

The U-shapedirame-i is mounted upon wheels 8 by stub axles 9; and havingits forward end mounted -upon theV casterw'heels l0. Stub shafts Ii arexedly secured to thel crossl channelY S'by` The sleeves I2 are ro-Vwelding or other means. tatably mounted to theV said stub shafts-andform apart of 'theupper bearing I3-ofvthe caster-whee1 assembly. Thisupper bearing is secured toV ther goose neck |4- o the* caster wheel'assemblies by the king bolt F5, operating `on the ball bear-- ings I6.

A locking pin Il passes through the sleeve l2 and the stub shafts-I I,best illustrated in Figures 3 and 4, holding'thecaster wheels eitherdown `as illustrated inv Figure 1 when the Asame is beingk operated byhand, or `in the broken line position when the same is being towed by atractor orv vehicle; Handle bars It are rotatably mounted withinthesockets I9, forming part of 'the' channel beam 3, referring to Figure9, and' locked in place by the set screw 20 operating withintheannularigrooves 2| of the handle bars. 'These handlebars can bemovedaround tothe Vbroken line position as indicated in Figure 5 while thehoist is being towed by a vehicle.

Mechanical brake drum assemblies 22 are associated with the wheels 8.These brakes are controlled by the cables 23 trained about the idlerpulleys 2d Within and underneath the cross channel 3. The ends of thesecables connect to the pivotally mounted lever 25, which in turn isoperated by the cable 26 running up through the handle bars, as bestindicated in Figure 9 to the hand lever 2, which is held in any desiredposition by the quadrant 28, referring to Figure 1. The brake can be setregardless of the position of the handle bars I8.

The hoist mechanism proper is housed in the horizontal housing 29,referring to Figures 6, 7 and 8. This hoist mechanism consists of a drum30, which is journalled to the cross shaft 3|, which in turn is mountedwithin the housing 29 the event that the load supported by the cable 39is relatively light, the crank 31 is applied to the countershaft 42which rotates the large gear 43, which in turn revolves the shaft 36through the small gear 44 at a relatively high rate of speed. This savestime, and is Van important feature relative to our hoist. Due to thefact that a worm wheel and a worm is used the hoist is self-lockingrequiring no additional braking.

Referring to Figures 1 and 2 particularly, we show a container 44 in theform of a box. This box is supported through the U-shaped strap 46 intowhich the hooks 41 of the cross beam 4l are hooked. This is only oneillustration of how the hoist can be applied to the load supported.

In the case of raising or lowering vaults, chains are usually loopedaround from each end coming together midway the length of the vault, ahook associated with thecable 39 is hooked into the same. Again we donot Wish to be limited to the exact use to which our hoist is adapted tobe used for.

In'the operation of our new and improved hoist in the removing of dirtfrom a grave, the hoist and the container 45 i5 wheeled up adjacent thegrave and the dirt shoveled therein, after which the hoist and load ofdirt is pulled back a suilcient distance from the grave to clear theburial operations. The hoist is removed from the container, which isthen covered over by a, cover, the hoist then being applied to the vaultfor lowering thesame, the wheels being far enough apart to straddle thegrave while rolling the vault thereover. These operations are usuallydone by hand through the use of the handle bars I8.

If a vault or load is to be removed to any great distance, we havesupplied a trailer hitch 48 for connecting to a tractor or vehicle.

Afterthe burial operation has been completed tl'ie'dirt container box 45is then picked up by the hoist and brought to the edge of the grave, V

the end 49 of the container 45 is raised, dumping the dirt into thegrave, the braking system of the hoist securely holding the hoist in thedesired location.

Our hoist is admirably adapted for the transferring of marker stones andthe like while yplacing the said stones. Our new and improved hoistwould be equally well adapted in garagework, removing motors fromvehicles or the like transferring the same to other parts of the shop.

Although certain specific embodiments of the invention have been shownand described, it is obvious that many modifications thereof arepossible. The invention, therefore, is not to be restricted except in sofar as is necessitated by the prior art and by the spirit of theappended claims.

.What We claim is:

l. A portable hoist comprising a U-shaped frame open at its rear end andincluding parallel spaced apart side bars connected at their front endsby a channel bar, vertical standards extending upwardly from the rearfree ends of the side bars, a housing supported on the verticalstandards, inclined braces connecting the upper ends of the standardsand the forward end of the side bars, wheels mounted on the rear freeends of the spaced apart parallel side bars, stub shafts extending fromthe ends of the channel bar, front wheels mounted on the stub shafts,means for holding the front wheels in raised or lowered position,hoisting mechanism in the housing, includingra drum and a cable, a U-shaped support to hold a container between the spaced apart side bars, abar at the end of the cable, and hooks at the ends of the bar to engagethe free ends of the U-shaped support.

2. A portable hoist as defined in claim 1, where-V in the verticalstandards are located in advance of the rear wheels, whereby When acontainer is held in the support the rear of said container extendsbeyond the rear ends of the spaced apart side bars.

3. A portable hoist as dened in claim 1, wherein the ends of the channelbar extend beyond the side bars and the stub shafts are fastened to theunderside of the channel bar.
